Hansen Gearbox Rebuild, Repair, and Emergency Services
Once your Hansen gearbox arrives at our
facility we disassemble, clean, inspect and measure all
gears and shafts and determine if your Hansen gears and
shafts are qualified to be repaired. If the Hansen gears and
shafts are not repairable, we have the capabilities
and expertise to manufacture all new Hansen gears and shafts
such as Helical, Double Helical, Herringbone, Split Herring
bone, Bevel, Spiral Bevel, Spur Gears, Ring Gears, Eternal
Ring Gears, Rack & Pinion, Worm Gears, Double Enveloping
Worm Gears, Hypoid Gears, Screw Gears, Plus More! Once your
Hansen gearbox is repaired we then do a six hour test
run for overheating, vibration, and leaking to ensure our 24
Month Guarantee. National Gear Box Repair can do all of
these repairs and rebuilds at a considerable amount of
saving rather than buying a new Hansen gearbox.
The Hansen Transmissions International of Belgium is one of the world's leading manufacturers
of wind turbine
Hansen Gearboxes .
The Company was founded in 1923 however it wouldnt
produce its first Hansen Wind Turbine Gearbox until 1979.
Hansen Gearboxes are large high tech and power dense components which require absolute
precision during manufacturing. The engineers who design these industrial solutions place a
high level of care during assembly and testing. Hansen Gearboxes have a special testing that
focuses on the
Gear Manufacturing process involving setting the tolerances at micron level
1/100-th of a millimeter which is even thinner than a strand of human hair.
Familiarity is key with the
Davis Standard and
Gloucester Gearbox Repair as similar design and
functionality was performed by Hansen as they created proprietary in house gear technology
allowing the Hansen Gearbox to exceed performance expectations beyond decades as the
various decades of experience improving the design of hansen gearbox is baked in to every
single Hansen Gearbox.
Hansen Gearbox also finalizes each gear through a hardening process known as gas
carburising. By heating the part to beyond 925 Celcius in a gaseous environment. Carbon
penetrates the surface as the temperature is dropped to 850 Celsius before being plunged into
an oil bath. The drop in temperature (referred to in the industry as “The Chill” gives the material
the required hardness.
What sets Hansen Gearboxes apart from other competitors like Davis Standard or Amarillo is
the proprietary testing system utilized by Hansen Gearbox Engineers. At National Gear Repair,
We understand that we may not be able to simulate the test bench used by Hansen in Beligum.
However as our mechanics are Certified through the Falk School and are Timken Bearing
Certified, They are no strangers to learning as much as they can about the variety of input
speeds, power ratings, load characteristics and other data they can use to fully understand the
rigorous test system in reverse to help reverse engineer and fix any faults within the Hansen
Gearboxes to allow us to complete our fast and efficient
